Have you ever encountered an issue where your computer shows an error message stating, "GtkWARNING ** cannot open display 0.0"? If so, you're not alone. Many people, particularly those who spend a significant amount of time using computers, have encountered this issue.

It's a frustrating problem because it prevents you from accessing certain applications or performing certain tasks. However, the good news is that there's a solution to this problem. The solution involves using a command called "sudo gedit," which helps address the issue.

For those who are not familiar with the term, "sudo" stands for "Superuser Do," and it implies that the user who enters this command has full administrative privileges. "Gedit," on the other hand, is a text editor application that comes pre-installed on many Linux-based systems.

So what exactly does "sudo gedit" do in relation to the "GtkWARNING ** cannot open display 0.0" issue? The command essentially allows the user to edit system files, including those controlling the way the computer displays visual information. This allows the user to modify the settings that are causing the error so that they can fix the problem.

To use the "sudo gedit" command, first, you need to open a terminal on your computer. Once you've done that, enter the command "sudo gedit /etc/environment" (without the quotation marks). This will open the "environment" file in gedit, allowing you to modify its contents.

Next, add the following line to the file: "export DISPLAY=:0". Once you've done that, save and close the file. You can then exit the terminal and restart your computer to see if the issue has been resolved.

In conclusion, if you're encountering the "GtkWARNING ** cannot open display 0.0" error, don't panic as there's a solution. By using the "sudo gedit" command to edit the system files, you can modify the settings that are causing the problem and fix the issue. Remember, always exercise caution when using terminal commands and ensure you understand what you're doing before proceeding.
